JOURNAL-BIOX.

SPECIFIGATIGN forming part of Letters Patent No. 597,797, dated January25, 1898.

ppiication filed May 27, 1896. Serial No. 593,328. (No model.)

.To all whom it may concern.-

Be it known that l, JOHN JOSEPH BURKE, a citizen of the United States,and a resident of Nanticoke, in the county of Luzerne and vState ofPennsylvania, have invented certain new and useful Improvements inJournal- Boxes, of which the following is a specification, referencebeing had to the accompanying drawings, forming a part thereof, in whichsimilar letters of reference indicate corresponding parts.

My invention relates to journal-boxes, and has for its object to providea device of this nature in Which a head is fixed upon the shaft tocooperate with the box and revolve therein.

In the drawings forming a portion of this specification, and in Whichlike letters of reference indicate similar parts in the several views,Figure l is a longitudinal section of a box constructed in accordanceWithv my invention, a shaft carrying a head being shown in elevation.Fig. 2 is a plan view of the lower portion of a box. Fig. 3 is aperspective vieuT of the box with the shaft in place. Fig. Il is aperspective view of the modied form of the head made in two pieces. Fig.5 is a plan view of the upper half of the head shown in Fig. 4. Fig. 6is a transverse section of line 6 S of Fig. l.

In operating in accordance with my invention I form a box comprising abase portion A and an upper cap or cover B, the result being a boxdivided centrally and horizontally.

In the base A. and longitudinallyT thereof I form a depression d,semicircular in crosssection, which depression is bounded at its ends byWalls A', which Walls form the ends of the box-base. In the end Walls A'are cut semicircular openings C2, as shown in Fig. 2,

forming, in connection with similar openings being normally closed bymeans of plugs F. The depression E is continuous, passing through thelower portions of the ribs d2 with the formation of arches cl3.

Upon reference to Fig. l of the drawings it will be seen that the upperportion B of the box is formed to cooperate with the lower portion, ribsd4, corresponding to ribs d2, being arranged above the latter. The ribsd4 are separated by a semicircularinterspace l), similar to thedepression CZ, While intermediate the ribs d'L and the ends of the capare angular depressions h4. The inner faces of the ribs d4 are unbroken.

Referring again to the ribs d2, as shown in Fig. 2 of the drawings, itWill be noted that grooves g are formed laterallyT of the upper facesthereof, Which grooves open rearwardly in pairs at opposite sides of thedepression d into connecting-grooves G, said grooves g terminatinginwardly at the annular faces of the ribs cl2 with iiarin g mouths g2.

In operatingl may form the head employed by me integral or in aplurality of pieces. If formed integral, I proceed by making a casing H,comprising a central cylindrical body havingV diminished ends h2,terminating in angular flanges h3. The central portion is provided witha series of hemispherical depressions K, and the entire device isslipped upon the bearing portion of a shaft C and held against rotationthereon by means of a key h or other suitable device. The operation ofthis form of my invention will be readily understood, and it Will beseen that upon placing the shaft C with its head Within the box thediminished portions h2 Will lie upon the ribs d2, the central portionwill lie intermediate the ribs d2, and the iianges h3 will lie in theangular grooves h4, the entire head turning with the shaft and havingbearing vupon the ribs d2 and the face of the depression d.

In oiling the oil is poured upon the central portion of the head throughan opening in the cap B, which opening is normally closed by means of aplug M or other device and lodges in the depressions K, through themedium of which it is distributed through the bearing-surfaces. Aportion of the oil also leaves the depression and passes into thegrooves Gr, from which it runs through g and upon the annular faces ofthe ribs d2. The

IOO

eXcess of oil of course runs to the bottom of the depression d, fromwhich it passes into the groove E and maybe drawn off wheny either ofthe plugs F is removed, spouts F2 f being provided to facilitate theoperation;

As shown in Figs. 4 and 5 of the drawings, if desired the head may bemade in two parts, in which casesuch parts maybe heldtogether by meansof screws w, the advantageof this construction being that Lin ythe eventof one section of the head becoming broken it mayy be removed andanothersnbstituted therefor;

f also,the head rmay be put into position withont removingthe shaft,which is not practical` kgeneral form without departing yfrom thespirit'ofA my invention.

Having fully described my invention, Iy

claimas new and desireto secure byLetters Patent f f t f f l. Thecombination of a journal-box having a central longitudinal bore oropening, a shaft or axle, the bottom portion of the box bein g providedwith a central semicircular chamber, an inwardly-,directed semicircularrib, at

each end thereof, between which and the en ds f of the box aresemicircular grooves, andthe rss upper portion of the boxbeing alsoprovided with a central semicirculargroove, a j'ournalhead on the shaft,said journal-head being cylindrical and tubular in form,y and beingksecured to said shaft, andA being provided at each end with tubularextensions, at the outer f end of each of which is an annular flange orrib, said parts being constructed, combined, and arranged, substantiallyas shown and described.

2. Thecombination of a journal-box having a central longitudinal bore oropening a shaft or axle, the bottom portion of the ,box

being provided with a central semicircular chamber, andinwardly-directed semicircular ribs, at each end thereof, between whichand the ends of the box or casing, are semicircular grooves, and theupper portion being also provided with a central semicircular groove7 ajournal-head on the shaft, said journal-head being cylindrical andtubular in form, and being secured to said shaft, and being provided ateach end with tubular extensions, at the outer end of each of which isan annular flange or rib, and the upper portion of said boX or casingbeing provided with a bore or passage through which a lubricant may bepoured onto said j ournal-head, and said journal-head being providedwith a plurality of cup-shaped cavities or depressions in the surfacethereof, substantially as shown and described. f

3. The combination of a yjournal-box having acentral longitudinal boreoropening, a

shaft or axle, the bottom portion of the box being provided with acentral semicircular chamber, an inwardly-directed semicircular rib ateach end thereof, between which and the endsofr the box or casing, aresemicircular grooves, and the upper portion being also provided .with acentrali semicircular groove. a j ournal-head on the shaft, saidjournal-head being cylindrical and tubular ink formand being keyed tosaid shaft, and being provided at each end with tubular extensions, atthe passage through which a lubricant ymay oe poured onto saidjournal-head, and said journal-head being provided with a plurality or'cup-shaped cavities or depressions in the surface thereof, 'and thebottom portion of said 'box or casing being provided with longitudinalgrooves adjacent to the central chamber :outer end of each offwhich'isanannnlar f flangek or rib, andthe upper portion of said iboX or 7casingbeing provided with a bore or formed therein,r into which the oil alsopasses` and Which communicates with grooves formed in the ribs at theend of said chamber, su ostantially as shown and described. f f

4. The combinationk of a baseportion A, a f

cap or cover B, both of which are provided with a longitudinalsemicirculargroove or recess to receive ka shaft, said base havingformed therein semicircular end grooves D, havinglongitudinal grooves oropenings,

screw-plugs F to close said openings, projectf ing lips F2, below saidopenings, semicircular ribs d2 forming a central chamber d, havinglongitudinal grooves G, in communication with transverse grooves g, saidribs d2, having formed in the curved surface thereof grooves g2,communicating with the groove g, said cap or cover having a semicircularchamber ZJ, and a journal-head H, a shaft carrying said head andprovided with tubular extensions h2, having annular ii-anges h3, fittinggrooves h4, in the cap or cover, said journalhead having cup-shapedrecesses and said cap or cover having an opening L, and a screwplug,substantially as shown and described.

In testimony that I claim the-foregoing as my invention I have signed myname, in presence of the subscribing witnesses, this 2d day of May,1896.
